# Nodes and components
Forms lets you add nodes and components, such as fields, blocks, and widgets for your users to interact with the form. You can then reference the data input, from components, in your forms and flows.
## Form nodes
There are five types of form nodes: Start, Step, Flow, Router and Ending screen. These nodes have a very specific purpose for the structure of the form.
## Step node
Step nodes are the visual representation of the form. They can contain any number of components, such as fields, blocks, and widgets where the user can fill in their data.

To learn more, read [Custom Field Components for Forms](/docs/customize/forms/custom-field-components).
### Blocks components
Blocks are UI components that add functionality to your forms but do not gather user information.
#### Available blocks in Forms
The available blocks are:
A button that lets users continue to the next form node.
* Before continuing, field validation rules are applied and validated on the client-side and server-side. If field validation rules fail, an error message is displayed for the user to verify.
* If the next node is a flow node, a spinner loader is displayed until the flow completes. If the flow fails or returns a custom error message, an error message is displayed.
A button that lets users go to the previous step node.
If a user selects the previous button, field validation rules are re-run again even if no change to input data is done before continuing.
A button that lets users skip the current step and directly jumps to the destination node.
When skipping the current step, we won't validate and neither collect any filled out information of the current step.
A component that lets users re-run a flow to generate and send a new OTP code
if a user selects the resend button, the associated flow will generate and send a new OTP code.
| Settings | Description |

| Flow | Flow executed after the user selects the resend button. |
| Max attempts | The maximum number of attempts the user can select the resend button |
| Waiting time | The waiting time between attempts in seconds. |

A widget that helps protect your website from spam and abuse by verifying that a user is a human and not a bot.
The widget supports:
* Score-based (v3)
* Challenge (v2)
* Invisible reCAPTCHA badge
Differences between `v2` and `v3`:
* `v2` requires user interaction with visible challenges, such as clicking a checkbox or solving puzzles.
* `v3` runs in the background and provides a score based on user behavior, without requiring user interaction. When using this version, make sure to implement additional business logic to handle the score and determine if further action is needed.

"hostname": "auth.example.com"
}
}
```

"score": 0.9
}
}
```

| Settings | Description |
| - | - |
| URL | The URL value used to generate the QR code. This value is returned in the `engagement` property of the verification request. |
| Link text | Alternative text that will be displayed for users who cannot scan the QR code and prefer to open the link directly on their device. |
| Size | The size of the QR code. |
| Public token | The access token required to consume the polling endpoint. Please ensure the token is generated with only the `read:verification_request` scope to avoid exposing access to other resources. |

"presentation": {} // The presentation contains the claims provided by the wallet in response to the presentation definition.
}
}
```
## Router node
Router nodes let you add rules to create conditional logic jumps between nodes.
By default, a router node has a single pass-through rule named **Default Case** that connects to other nodes. You can add additional rules based on a set of conditions that a variable must meet to then connect to other nodes. To learn more, read [Router.](/docs/customize/forms/routers)
## Flow node
Flow nodes let you add and create custom logic and integration flows to your forms. To learn more, read [Flows.](/docs/customize/forms/flows)
## Start node
Start nodes are not visible to the user. It is where you can configure hidden field variables, such as user attributes when [rendering a form with an Action.](/docs/customize/forms/render)
## Ending screen node
Every form has an Ending screen node. By default this node resumes the authentication flow and this is where you can configure an After submission flow.
